If you inadvertently initialize more elements or variables than exist in an array, SAS generates a warning For example, the following DATA step defines two arrays,

Basic Syntax of the ARRAY Statement To use arrays in SAS code first make sure that you understand the basic syntax of the SAS ARRAY statement This section describes the ARRAY statement and provides a number of examples to illustrate its use Subsequent sections progress to more complex statements and examples
SAS ARRAY is a set of variables of the same type called “elements” of the arry that you want to perform the same operation on An array name is assigned to the set of variables Then the array name is reference in other DATA step programming to do an operation on the entire set of variables in the array
SAS ARRAY is a set of variables of the same type called the “elements” of the array that you want to perform the same operation on An array name is assigned to the set of variables and then the array name is referenced in later DATA step programming usually a DO loop to do an operation on the entire set of variables in the array
A SAS array is a convenient way of temporarily identifying a group of variables for processing within a data step Once the array has been defined the programmer is now able to perform the same tasks for a series of related variables the array elements Once the basics of array processing are understood arrays are a simple solution to many program

What is array in SAS?
As a result, arrays are typically referred to as either character arrays or numeric arrays. Variables that are associated with an array do not have to be already existing variables. If they do not exist within a program data vector (PDV) when the ARRAY statement is compiled, SAS creates them for you.
Can a SAS code be written without arrays?
In nearly all cases, code that is written with arrays can also be written without arrays. Arrays simply provide an alternative method for referring to a variable rather than using the name of the variable. To use arrays in SAS code, first make sure that you understand the basic syntax of the SAS ARRAY statement.
How does SAS determine the number of variables in a weight array?
Notice the asterisk (*) inside the brackets in the WEIGHT array above. SAS must be able to determine the number of elements or variables in the array when it compiles the code. SAS determines this either by using the constant value that is specified in the brackets or by counting the number of variables in the variable list.
What are the delimiters of array-elements in SAS?
Array-elements in the SAS software data step array statement are assumed to be delimited by spaces. When array-element values are provided to this routine as a list, the macro scan function is used to pick out each value. The delimiters of the macro function %scan are the set of non-alpha-numeric characters.
